★★☆☆☆
I tied various concentrations but in the end it didn't work. I used bleach that has nothing else in it because I heard there are other kinds with other chemicals that can burn the skin.
I applied it for over a month, twice a day, for about 1 hour, then washed it off and applied Lamisil.
It dried the skin, it seemed to make Lamisil work slightly better, but in the end it didn't work.
